My code here reads a users input greather than or equal to three. (As per the assignment requirment). The only problem I am having is that when I run the code (Say the user enters 13), it returns 3 4 5 7 11. Every other number is correct, but I can't for the life of me figure out why it keeps returning a 4. Any tips/advice? Thanks!
